SPECIFICATION forming part of Letters Patent No. 414,129, dated October29, 1889.

Application filed March 5, 1889. Serial No. 301,867. (No model.)

To all whom it may concern.-

Be it known that I, EMERY VAN DECAR, a citizen of the United States,residing at East Albany, in the county of Rensselaer and State of NewYork, have invented certain new and useful Improvements in Lubricatorsfor the Journals of Railway-Axles, of which the following is aspecification.

My invention relates to improvements on a I0 lubricator for journals ofcar-axles invented by myself and forming the subject-matter of anotherpatent; and it consists in combining with the cushionedlubricating-cylinder and the journal of the axle gearing mechanismthrough which the revolving of the axle will impart motion to thelubricating-cylinder before referred to.

The objects of my invention are,primarily, to so combine with thecushioned lubricating- 2o cylinder and the journal to be lubricatedgears through which motion will be positively transmitted to thelubricating-cylinder to revolve the same, whether the oil in the boxsurrounding the journal be cold and thick, as

2 5 in weather when the temperature is below zero, as well as in warmweather; second, to provide a specific construction and combination ofparts by which this improved device can be readily applied and becommunicated from the revolving axle to the lubricatingcylinder, and themechanism intervening between the two being held in place and not liableto get out of order. I attain these obj ects by the means illustrated inthe accompanying drawings, forming a part of this specification, inwhich- Figure 1 is a side elevation of the journallubricating cylinderand gear mechanism employed. Fig. 2 is a sectional elevation of thesame. Fig. 3 is an end elevation. Fig. 4 is a view showing amodification of manner of holding the driving gear-wheel in connectionwith the axle.

; The same letters of reference refer to like 5 parts throughout theseveral views.

In the drawings, A is the axle. B is the journal thereof. 0 is the boxincasing the journal, and D is the brass bearing of the same, all ofwhich are of any suitable construction.

When the axles of railway-wheels are to be turned and finished withjournals in the usual manner practiced by the trade,- centering holes orperforations a (indicated by dotted lines in Figs. 2 and 4:) are drilledendwiso in the journal ends of the bar from which the axle is made, andfrom Which the bar or axle will be centered in the lathe for turning andfinishing. This centering hole or perforation a is made generally ofdiameter of one-half an inch (more or less) and with a depth of half aninch or more from the end surfaces, so as to receive the centers of thelathe on which the axle is to be revolved. In this invention I availmyself of the use of these central perforations thus produced in theends of the axles for centering and contributing to the holding of thedriving-gear with the axle.

E is a drive-gear made of suitable diameter and having its teeth or cogswith long pitch.

This gear has made with it from its rear side the central stem 6, ofdiameter and form to correspond, substantially, with the Walls or insidesurfaces of the walls of the central perforations a in the ends of thejournals of the axles, so as to nicely fit in the same without liabilityof shifting laterally. In some cases I form with this central projectionor stem 6 of gear E a feather e, and when this feather is used I cutfrom the metal surrounding the central perforation a a small slot ofsize and form corresponding, substantially,with that of the saidfeather. By means of this feather this gear will be keyed from twistingor turn ing loosely around in relation to the axle with which it isconnected. This gear E is preferably pierced at one or more placesthrough its back web 0 for receiving an attaching screw or screws d, anda screwthreaded hole 61', corresponding with the screw 01, is made inthe axle from its end and receives said screw, and by it this gear E isse cured tightly against the end of the axle.

F is a second gear having its cogs or teeth made with a length of pitchcorresponding 95 with that of gear E, and is secured to the axle orspindle f ,of the cushioned lubricat ing-cylinder G, and is fixed tosaid spindle, so that when it is revolved the spindle and the cushionedlubricating-cylinder will be revolved with it. The ends of the shaft orspindle f, towhich this gear F is secured, is supported in elasticbearings g, secured to track:

ets or elastic arms of the lubricating-cylinder support H, and can besubstantially made as in my former invention or in any other suitablemanner. These bearings are made to have connection with the body of thelubricating-holder H, so that the lubricatingcylinder will beelastically supported with its surfaces against the lower side surfacesof the journal of the axle, with the gear F in gearing with the gear E,secured to the axle. V The drawings show the drive-gear E to be madewith a width of or greater than the width of the face of the driven gearF." This increase of width of face of gear E is provided so as to allowan endwise play of the axle, as is commonly had while cars are runniiig,and so that while the journal of the axle can have a relativelylongitudinal play in relationto the box inclos'ing the. same thecylindrical lubricator containedin the boxO will not be moved nor thegear E be carried out of engagement with the gear F, secured to theshaft of the lubricating-cylinder G. I prefer to make the gear E withthis greater width of face to such an extent that when the brasses havebecome worn at their ends", or the shoulders of the journals becomeworn, or both, an increased endwise play of the journal will bepermitted without affecting the gearing mechanism; The teeth or cogsofthe gears E and F are made with a long pitch similar to I that employedwith gears of wringing-machines and of rolls, so that when the brasses Dbecome worn and the axle or journal has been per mitted, to risecorrespondingly and relatively from the floor of the box 0 the teeth orthe cogs of the respective gears will not become disengaged by theraisingof the cogs of the gear E in relation to those of gear F; In somecases, Where the distance between the end'of the axle and the box is soshort that it would be inconvenient to readily introduce a.lubricating-cylinder G of full length in place between the lower side ofthe journal and floorof the box, I Vmake the lubricatingcylinder insections of two or more, as sections 1,- 2, 3, 850., (shown in Figs. 1and 2,) which sections can be readily slipped on the spindle or shaftfvof said lubricating-cyliiider, and by any suitable known means thesetwe or. moresections will be held locked with said shaft; so as to turnwith the same.

i'As a ready and efficient means for holding these sections locked withthe shaft, a square A form of shaft; with square holes in the hubs,

can be employed, or a shaft with a continuous feather made with it, andcentral perforations having keying slots in the hubs of these sectionscan be employed, or any "other means canbe used by which these sectionswill be securely held with the body of the shaft. In these cases theends of the shaft f will be made of cylindrical form for revolving inthe bearings of the device supporting the cylinder."

By my above-described improvements the lubricating-cylinder G will begeared with the end of the axle in a secure manner and central inrelation to the same, and can be readily applied to all axles with butlittle expenditure of labor, and when applied will be in condition inwhich the mechanism will not be liable to get out of order while inordinary use, and the axle be allowed to have its usual endwise motionin reference to the box containing the same, without being affected, andthe brasses be employed for the same length of time they are usuallyemployed without being renewed and without affecting the gearing; Withthese improvements the lubricating cylinder will be positively revolvedwhen the axle is revolved;

It is well kn own that mineral oils usually employed for lubricating thejournals of axles on railway-cars become stiff and thickened in coldweather,- and in some instances, in extreme cold weather, while thisstifiening of the oil might operate, to hold ,the lubricating-cylinderfrom being revolved by the contractive force or friction between thelubricating-cylinder and the journal, thus gearing the said cylinderwith the journal, will obviate all liability of the former being heldfrom turning. t a

By this above desc'ribed mechanism the cylinder G will be revolved atthe first movement of the axle, and will be continued to revolve duringall the time the axle is r'evol'v'ed, and the moving force applied tothe lubricating-cylinder through the gears E and F from the revolvingaxle will be sufficientto overcome the resistance offered by thestiffened and thickened oil, and the said cylinder will be forced tocarry up the oil adhering to itssurface to the surfaces of the axle.When, after a few revolutions, the axle becomes warm, the oil within thebox will also become raised in temperature, and the lubrieating devicewill be made to work effectively 'to supply oil to the journal.

foration and provision for holding the gear from turning in relation tothe end of the journal, substantially as and for the purposes setforth;a r

2. The combination, with the journal end of the railroad-axle, of alubricating-cylinder composed of two or more independent and separatesections which can at will be applied to a common shaft and revolved incontact with the lower side of the journal of the axle, gear E, securedto the end of the axle so as to revolve with the same, and gear F,secured to the shaft on which the several sections of thelubricating-cylinder are mounted, substantially as and for the purposesset forth.
